3.2 Structure density during storage
Immediately after 60 min of cooling, where significant differences in microstructure were observed
between the seeded and non-seeded samples, diffusion measurements with FRAP and HPLC were
initiated to correlate the quantification of structure density with the results of the microstructure
characterization. The results presented here are adaptations of what has been published in [16].
The calculated local diffusion rates of BODIPY, obtained from FRAP measurements, for all chocolate
model systems after 60 min of cooling and after one week of storage are presented in Figure 3. Directly
after cooling, the non-seeded samples had significantly higher local diffusion rates of BODIPY compared
to the seeded samples. However, for the non-seeded sample with CB+sug the standard deviation was too
